To all whom t T11/Ly concern,.- f

Beit known that I, JAMES EDWARD HUEY a citizen of the United States,residing at Charlotte, in the county of Mecklenburg and 'State of NorthCarolina, have invented eertain new and useful Im rovements in Door-Pivoting Devices; and do declare the 'following to be a full, clear, andexact descri tion of the invention, such as will enab e others'skilledin the art to which it apperitains to make and use the same.

My invention relates to improvements in door-pivoting devices which areadapted to hang and support a door so that the same may be opened fromeither side and which operate automatically to normally retain the doorin a closed position and to return the door to a closed positionafter'it has been opened; and my invention consists in the construction,combination, vand arrangement of deviceshereinafter described andclaimed.

In the accompanying drawings, Figure 1 is a vertical sectional view showing a door-frame, a door, and my improved pivoting devices for thedoor, the latter being indicated in a closed position. Fig. 2 is asimilar view taken on a 'plane at right angles lto that of F andindicated by the line afa of said Fig. 1. Fig. 3 is a detai sectionalview taken on the plane indicated by the line b b of Fig. 1. Fig. 4 is adetail top plan view of the lower member of the lower pivoting device.Fig. 5 is an inverted plan view of the upper member of the lowerpivoting device. ig. 6 is a sectional view of a door and door-frameprovided with modified forms of my door-pivoting devices, and Fig. 7 isa detail sectional view taken on the lane indicated by the linee c ofFig. 6.

T ie door is indicated atl.

2 indicates a side jamb of the frame, 3 the top jamb, and 4 the carpetstrip or sill.

The lower pivoting device comprises the lower member 5, the upper member.6, and the supporting bearing-balls 7. The lower.

member 5 has a base-plate 8, which is rectangular in form and either ofthe longer sides of which may be placed against the side jamb 2, thesaid plate being recessed in the carpetstrip and secured in place bymeans of screws, the said plate 8 being provided with screwholes 9. Onthe center of the upper side of the plate 8 is a cylindrical boss 10,from the center' of which rises a pivot-stud 11. In

the upper side of the said boss on opposite ,I sides of the saidpivot-stud and concentric therewith are .two segmental' grooves 12,wnich are provided with oppositcly-inclined cams onWedge-surfaces 13,the said grooves being deepest at their central portions mid--l waybetween their ends. The upper member 6 ofthe lower pivoting devicecomprises a web 14, which has an inclined upper edge 15. Said uppermember has on the lower side of the said web at the outer end thereof,

A a cylindrical boss 16, having a depending cy- 'lindrical flange 17,that .lits over the cylindrical boss 10 of the lower member 5.

In the under side of the boss 16 are segmental grooves 18, whichcorrespond with the grooves 12 of the lower member and registertherewith, the bearing-balls 7 being retained in the said grooves 12 and18, as shown in Fig. 1. The said upper member 6 has a vertical opening19 to receive and form a bearing for the pivot-stud 11 of the lowermember. The web 14 is here shown as rovided with a downwardly-inclinedcharme 20, which leads to the upper end of the opening 19 and enablesoil to be ,applied to the bearing formed by said opening and thepivot-stud 11, as will .be understood. In the upper side of the web 14is a notch or recess 21.

' The door 1 has one of its lower corners recessed, as at 22, to receivethe web' 14. Said recess is Open at the lower and inner edves of thedoor, and the top of said recess is inc ined, as shown, to bear on theinclined upper edge 15 of said web. The cylindrical boss 16 of vthe uper member 6 is fitted in a countersink in the ower portion of the doornear its inner pivotal side.

To facilitate the placing of the door on the upper member 6, the upperside of the shoul-'V der formed by the lateral projection ofthe boss 16beyond the sides of the web 14 is inclined, as indicated at 23 in dottedlines in Fig. 1. I also employ'a air of plates 24, which are shown indotted lines in Fig. 1 and in cross-section in Fig. 2, which plates bearagainst opposite sides of the door so as to cover the recesses made forthe rece tion of the upper member 6 and present a sig tly a pearance.These plates are secured to t e door by means of screws 25 near theirinner ends. They are also comiected together near theirouter ends by ascrew 26 and a screwsleeve 27, each having a head, as shown, to

IOO

' at the upper, inner, or pivotal corner thereof bear against the outerside of one of the plates, l the said screw engaging the threaded boreof i the screw-sleeve and coacting therewith to clamp the plates onopposite sides of the door. The notch or recess 2l in the web 14 servesto clear said screw and screw-sleeve, (which are placed in a transverseopening in the door,) and the latter enable the plates to be secured onthe opposite sides of doors of varying thicknesses, so that my improvedpivot devices may be employed on doors of any thickness.

It will be understood, upon reference to 1, that the segmental groovesof the upper and lower members ofthe lower pivoting device register witheacli. other when the door is in a closed position and when thebearing-balls 7 are in the deepest central portions of said grooves. Itwill be further understood that when the door is turned in eitherdirection the angular movement of the upper member on the lower memberwill cause the coacting cam or wedge surfaces of the grooves to move thebearing-balls in one direction or the other, corresponding with themovement of the door, and that as said bearing-balls traverse the camsor inclined surfaces of said grooves they will cause the upper' member 6to be raised from the lower member and the door to be raised with suchupper member. It will also be understood that when the door is releasedsaid coacting camsurfaces of the grooves of the upper and lower memberswill c'oact with the said bearingballs 7 by reason of the weight ordownward pressure of the door to return the latter automatically to itsnormal closed position.

The upper pivoting device comprises the lower member 28 and the uppermember 29. The lower member 28 has a cylindrical boss 30, the base ofwhich is countersunk in the upper edge of the door, as shown in Fig: 1.From the said boss depends a cylindrical sleeve 31, the lower end ofwhich is closed by a removable plug 32, the latter being here shown assecured in place by a pin 33. In the said sleeve is a bearing-screw 34,which is also an adjusting member. Said screw has a head 35, provided inits upper side with a bearing and center socket 36. On the threaded stemof the screw is an adjusting-nut 37, which bears on the upper end of aspring 38, the lower end of which bears on the plug 32. Said springexerts a downward thrust on the door to add to the downward pressure ofthe door on the lower pivoting devices and to supplement the gravitatingaction of the door. The sleeve 31 is mortised in the door, and a screw39 is employed to secure the lower member 28 of the upper pivotingdevice to the door, as shown in Fig. 1-. I also provide a pair of plates40- which are secured to the opposite sides of the door to form a finishfor the same. The upper .member of the upper pivoting device comprises aplate 41, which'corresponds in size and shape with the platei8, andacylindrical depending sleeve 42, which receives the cylindrical boss 30of the lower member 28. 7o

From the center of the said sleeve 42 depends a pivot-stud 43, the lowerend of which engages the bearing and centering socket 36 of theadjusting-screw 34.

It will be understood that owing to the 45. These stop-strips, owing totheir beveled or opposite sides, afford a clearance 'for the door as itmoves upwardly and downwardly and also closes the crack above the doorwhen the latter is closed.- (See Fig. 3.)

I will now describe the modified form of 9o my invention shown in Figs.6 and 7. The

lower pivoting device comprises the upper member 46, which isalniostidentical in construction with the upper member 6, hereinbeforedescribed, and the lower member 47.

In coaction therewith I lemploy a pivoting and adjusting screw 48, afollower 49, an ad-t justing-spring 50, and an adjusting-yoke 57. Thelower` member 47 has a depending cylinder 51, in which operates thefollower 49 roo and the adjusting-yoke 57. The follower 49 has the camor wedge surfaced grooves 58 in its upper side corresponding with thesimilar grooves 59 in the lower side of the upper member 46 to receivebearing-balls 60. The 105 adjusting-yoke has lugs 52, which operate ingrooves 53 in the sides of the cylinder. The upper end of the screw 48is angular in form, as at 54, to enable it to be turned by a Wrench.Near its upper end said screw has i io an annular flange 55, which isreceived in countersunk recesses 56 57a in the opposing sides of themember 46 and follower.49, so that said screw is prevented from movingvertically with relation to said member 46, [15

but when turned by reason of the engagement of its threads withathreaded opening in the adjusting-yoke 57 through which it extends,causes said adjusting-yoke to move upwardly or downwardly, according tothe rzo direction in which said screw is turned. The spring 50 is hereshown as a coiled spring, with its ends respectively engaging the underside of the follower 49 and the adjusting-yoke 57, so that its tensionis varied by the movement of the adjusting-yoke to cause it to pressupwardly under the follower 49 with any desired degree of force, andhence cause said follower to coact with the bearing-balls 60 and theupper member-46 13o To obviate 8o to normally close the door and tonormally retain the door in a closed position. It will be understoodthat the door in this form of my invention does not move vertically,said movement bein@ made by the follower 49. At the lower end ofthescrew 48 is a nut 61, which after it has ybeen adjusted is secured tothe screw, as by a pin 62. The upper pivoting devices comprise,essentially, a stud 63 on a member 64, secured to the door, and abearing sleeve or recess 65 in a member 66, secured to the upper j amb.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages ofthe invention will be readily understood without requiring a moreextended explanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of the invention as defined by theappended cla ms.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An upper doorivoting device comprising a lower member avi'ngacylindrical boss,

a cylindrical sleeve depending therefrom, a removable closure for thevlower end of said sleeve, a bearing-screw in said sleeve, having a headprovider' with a bearing-socket in its upper side, an adjusting-nut onsaid screw, and a spring in said sleeve bearing under said nut; incombination with an upper member, having a cylindrical depending sleeveto re ceive the cylindrical boss of the lower member, and a pivot-studto extend into the bearing-socket of the screw of the lower member,substantially as described.

2. In combination with a lower door-pivoting member, anupperdoor-pivoting member having a web provided with an inclined upper sideand a clearance notch or recess, a door having a recess in its lower,inner corner, for the reception of the said web, plates on oppositesides of the door, and a clamping device for the said plates, cleared bysai notch or recess in said web, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
